- Rounding edge fillet surface will be created. (for both a part body and an open body) - Robust creation of a fillet surface even for complex shape. - Extensions to “Edge fillet” of CATIA are as follows. Chord Chord length length Fillet arc calculation: Fillet arc calculation: ball, spine or normal plane ball, spine or normal plane Independent end shape Independent end shape processing for each end processing for each end Independent extension Independent extension for each end for each end Adjustment of broken Adjustment of broken edge angle edge angle Adjustment of broken Adjustment of...

(1) Constant or variable can be selected for radius and chord length. R [constant radius] [constant chord length] [variable chord length] (2) Ball/spine/plane can be selected for circular arc calculation. Spine curve [Ball] Ball rolling circular arc between two surfaces [Spine] Circular arcs are on the planes normal to given spine curve. A plane with given normal vector [Plane] Circular arcs are on a plane normal to specified direction.

Different width for each end A fillet surface is created so that distance from an edge to an R end curves is different from one of the other side. All Rights Reserved, Copyright(C) 2009 Nihon Unisys, Ltd.

Face fillet - Create a fillet surface by specifying two sets of surfaces and radius or chord length (constant/variable). - M * N surfaces input is available for support surfaces. - Extensions to “Face fillet” of CATIA are as follows. Chord Chord length length Face – face Face – face fillet fillet Shape fillet Shape fillet Edge Edge distance distance Fillet arc calculation: Fillet arc calculation: ball, spine or normal plane ball, spine or normal plane Independent end shape Independent end shape processing for each end processing for each end Independent extension Independent extension for...

Face fillet - Variation of fillets is the same as Rounding (1) Constant or variable can be selected for radius and chord length. R [constant radius] [constant chord length] [variable chord length] [constant edge length] [variable edge length] (2) Ball/spine/plane can be selected for circular arc calculation. Spine curve [Ball] Ball rolling circular arc between two surfaces [Spine] Circular arcs are on the planes normal to given spine curve. A plane with given normal vector [Plane] Circular arcs are on a plane normal to specified direction. All Rights Reserved, Copyright(C) 2009 Nihon...

Curve fillet - Create a fillet of which one or both sides are bounded by a curve. - Variety of fillet surfaces can be created by the combination of ‘pass through type’ and ‘fillet type’. - Sweep command is used for this purpose in CATIA. Extensions to CATIA’s sweep function are as follows Chord length Chord length Fillet arc calculation: Fillet arc calculation: ball, spine or normal plane ball, spine or normal plane Curve/surface fillet Curve/surface fillet Substituted by Sweep command Independent end shape Independent end shape processing for each end processing for each end Independent...

Curve fillet - A Fillet surface can be created between two or more faces without any preparation (connection, extraction, etc.), regardless of status of the connection or disconnection of the faces. [Pass through type] [Curve on surface] [Curve-surface] “Tangent to a surface” “Pass through a curve” [Curve-curve] “Pass through curves on both sides” [Fillet type] “Pass through a curve and tangent to a surface” “Tangent to a surface” “Pass through a curve and tangent to a surface” “Pass through a curve” “Pass through curves and tangent to surfaces” Constant-R, variable-R, constant chord length...

Three tangent fillet - Create a fillet surface tangent to three groups of surfaces. - Difference from “three tangent fillet” of CATIA is that two or more faces can be input for each support. - A Fillet surface can be created between two or more faces without any preparation (connection, extraction, etc.), regardless of status of the connection or disconnection of the faces.

Batch Fillet - Collective creation of fillets Specifying R value to each edge among edges. - Start and end points of each fillet can be specified separately. - Method of fillet embedding can be specified. Batch Embedded fillets makes an intersection shape. Secondly created fillet extends to another edge because the corner is rounded by the result of embedding of firstly created fillet.
